Patented June 2, 1931 UNITED STATES ALBERT F. TEICHMAN AND JOHN W. THEE,OF CINCINNATI, OHIO WATER CONTROL DEVICE Application filed March 2,

This invention relates to a water control device and has for an objectthe provision of a device whereby an accurately measured quantity ofwater may be automatically delivered from a supply pipe to a tank orcontainer and retained therein for subsequent rapid discharge into anysuitable receptacle such mixer.

An object of the invention is to provide a water control device whichmay be conveniently mounted on practically any approved type of concretemixer and one which is adapted for automatic co-operation with suchmixers to the end that a predetermined quantity of water is alwaysavailable for automatic discharge into the mixer when cement andaggregate material from a loading hopper are discharged into the mixer.

Another object is to provide means for the purposes stated'which sofacilitates the operation of properly mixing cement and aggregatematerial with the proper quantity of water as to encourage the use ofthe automatic mechanism by the operator.

Another object isfto provide a device of (his kind with means vwherebyintentional mis-use of the'device may be rendered difficult and readilyobserved by a supervisor.

These and other objects are attained by the means described herein anddisclosed in the accompanying drawings, in which:

The device of the invention, independent of a mixer or other mechanismto which it may be attached, comprises a suitable supporting frame whichmay be constructed of suitable spaced angle or channel members 11 fromwhich a bracket 0r upright structure 50 12 extends. The uprights 12 maycarry suit- 1928. Serial N0. 258,652.

able cross members 13. F ulcrums or roller bearings 14 are mounted uponupwardly projecting portions ot members 12 pivotally supporting a beamstructure. The beam structure comprises a bar 15 having a transverse 5member 16 from the opposite ends of which extend arms 17. The beamstructure comprising the members 15, 16 and 17 will hereafter bereferred to as beam 18 upon which is adjustably mounted a weight 19. Atthe ends of the arms 17 of beam 18 are depending links 20 which supporta tank member 21. The arms 17 are pivotally mounted on the rollerbearings 14 intermediate their opposite ends, the weight 19 normallyretaining the 65 tank in a raised position. The tank 21 is preferablyprovided with an inclined bottom 22 having an apertured discharge tubev23 secured thereto and supplied upon its upper face with a suitablegasket member 24. 7u Interiorly of the tank 21 are provided lugs 25through which extend pintles 26 for hingedly mounting a` valve 27. AbovetheV discharge tube or aperture 23 and across the top of the tank aresuitable transverse members 28 to the underside of which is secured asuitable bearing S29-for the end of a rod 3() which also finds a4bearing at 3.1 in an end wall of the tank 21. l

Rigidly secured to the rod 30 is an arm 30 32 the end of which haspivotally attached to it a. link 33. The link 33 has a pivotalconnectionat 34 with the valve 27. Oscillation of rod 30 b means of crank handle35 serves t-o lift and lower the hingedly mounted valve 35 27 foropening and closing discharge pipe 23.

A water supply pipe 36 is fixedly mounted adjacent the tank 21 and has avalve controlled spout 37 overhanging the tank. The valve 38 may be ofthe whistle valve type, 90 provided with a weighted lever 39 with aroller 40 on its free end and adapted to normally retain the valve inclosed position when lever 39 is in av lowered and unsupported position,as shown in Fig. 3. A cam 41 is xedly mounted on rod 3() in suchposition that it may operate, upon movement of the rod about its axis,to abut the roller 40 and raise lever 39 to open valve 38.

However it will be noted that. because of the suspension of the tank 21upon beam 18,

the tank will. rise and descend bodily accordingly as the weight 19overbalances the empty tank, lor the tank, filled with water from`nozzle 37 overbalances the weight. The rod 30 journalled in the tankmoves bodily with with valve 38 open. From the foregoing it will benoted when the tank is filled withv water sufficiently to overcome theweight 19 in its adjusted p posit-ion, an accurately weighed quantity ofwater is in theV tank and the supply shut off by the descending movementof the tank.

The filled tank now iemains ready to r be almost instantly dischargedupon opening of valve 27 by turning rod 30 about its anis by means ofhandle crank (see'Fig. 3).

When the tank is thus emptied the weight 19 again raises the tank androd 30, but, so long as handle 35 remains in position` to hold valve 27open, cam 4,1 cannot touch roller 40 toV raise valve lever Y 39.Movement of handle crank 35 inthe opposite direction completelycl-osesrvalve 27and then opens valve 38 by means of the cam 41. Thestructure thus far described is of general application and may be usedto advantage by manual operation of lhandle crank 35 in many Yinstances.

The lsimple mechanism shown in Fig.V 4 may be associated with the devicejust described and the combined structures applied 'i to a concretemixer so that automatic operation ofthe device is attained through theagency of the loading hopper as it raises to discharge cement andaggregate material into the mixer and is low-eredto receive a new batchof said materials.

As shown in' Fig. 4 a pivot bar 42 having rigidly secured toit an arm43-is provided with a pivotal bearing at 44 upon cross member 13. Thisbearing is substantially zin' alignment with the axis of rod 30fand isslightly above it. VArm 43 lies directly over Y the handle crank'35 towhich Vit has an anti- :sol

friction .connection through yoke 45 rigidly attach-ed to arm 43. Theyoke carries a pair of spaced rollers 46 between which the handle crank35 extends so that when the arm ,and handle crank are rotated abouttheir several spaced axes the connection between the two members isretained and the movement of the handle crank 35 relative to the yoke 45takes place with aminimum of friction. From the foregoing it will beapparent that by impartingtilting movement to pivot bar 42 about itsfulcruni or pivotal mounting 44 the handle crank 35 may be manipulated.As will be noted in Figs. 1 and 4 the pivot bar 42 has a counter-weight47 which normally drops to adjustable stop 48 so as to 'dispose the arm43insubstantially a-vertical posi-V v tion. In this positionthe arm 43holds the the water supply valve 38. It should beV noted that in thisposition the valve 27 is tightly closed. As shown in Figs. 1 and 5 ashaft 480 is mounted in spaced bearings 49 carried by vupright members50 which form part of the supporting structure upon which loading hopper51 is mounted. The shaft 480 carries a short rocker arm 52 having aroller 53 thereon adapted to be engaged by a plate 54 carried by.loading hopper 51 as it moves about its pivotal mounting at 55. Theloading hopper in the present embodiment is power actuated in itsraising and lowering movements and is controlled by means of a throttlelever or clutch lever not shown. The shaft 480 also has a long rockerarm 56 rotatable therewith by means of a pin 62 normally disposed in aslot in sleeve 64 which is integral with arm 56 so that whenthe vhopper51 raises and moves short rockerV armVV 52 through an arc, the longrocker arm 56 is lowered. An adjustable*connecting link 57 having asuitable clevis 58 at each end which are pivotally mounted to the longYrocker arm 56 and the ,end of pivot bar 42 respectively, serves toautomatically move the arm 43 and crank handle 35 whenever the hopper 51is raised to discharge into the mixer 59; When discharge tube 23 of tank21, while its oppositeend is inserted in the rotatingmixer drum 59 todirect the flow in any desired manner within the drum; l f

This automatic actuation of the tank may be' rendered inoperativethrough the mechanisin shown in Fig. 5 wherein handle 61V carrying pin62 is pushed forwardly against the resistance of spring 63 so that thepin' 62 moves out of the slot in sleevev 64 and into the connecting slotin sleeve The handle 61 is then rotated to the position shown in dottedlines in Fig. 4and the short rocker arm 52 is moved up and .outrof thepat-h of the hopper 51. It should be noted. that the end of handle crank35 extends beyond the arm 43 Vso that when the automatic operationisthrown out as explained, it may be manually?l controlled by the handlecrank The operation of the device is as follows. Assuming that the watersupply pipe 3,6 is connected Ywith a suitable source of water supply andthe part-s are in position shown in Fig. 3 wherein the tank 21 hasdischarged its contents into the spout 60. With the automatic feature inoperation, theloading hopper 51 is in a iraised position at such iinevtodischarge cement and aggregate maiin izo

teria-ls into the mixer' 59. As soon as the tank has discharged itscontents the weight 19 will drop, raising the tank bodily. It should benoted that at this time the lever 35 is still in the position shown inFig. 3 wherefore rod 30 and cam 41 are also in the position shown inthat view. The valve 27 also remains open. At this time the weighted endof the pivot bar 42 is raised, being held in that position by the actionoi the hopper 51 through the short and long rocker arms and connectinglink 57. IVhen the hopper is lowered, Weight 1-7 moves pivot bar 112about its fulcrum 44 raising long rocker arm 56 by means of theconnecting link 57. At this time the arm /13 moves with the pivot bar 42and turns the rod 30 about its axis by means of the handle crank.

It should be noted that when the tank is discharged it is in an elevatedposition because of the counterbalance 19; therefore relativelongitudinal movement takes place between the arm 43 and handle crankIVhen the handle crank 35 is brought to vertical position it will benoted that the valve 27 will close due to the action of arm 32 and link33 and immediately following the closing, the cam 41 will be moved aboutits axis to encounter the roller 40 to raise lever 39 and to open watervalve 38. Tater then flows through the pipe 36 into the tank 21 untilthe tank contains a sutficient quantit-y (by weight) of water to tip thebeam structure 18 about its pivotal mount-ing at 14 so that the tankdescends bodily to encounter a stop and suticiently to remove the cam 41from lever 39. Thus the water supply is automatically shut olf.

A suit-able seal, padlock, or the like (not shown) may be employed toprevent accidental or intentional movement o'l" weight 19 from itspredetermined adjustment on the graduated lnember 15 of beam 18. Themarkings or graduations 15() may indicate net units of weight of waterin the tank, when tank and weight 19 attain a position of equilibrium.In this way the device may be adjusted by a superviser or responsibleemployee. The Water ratio theory, with which those versed in the art arethoroughly conversa-nt, may be put into actual practice withoutnecessitating the employment of skilled labor.
